Dual nature of magnetism in MnSi

The dual nature of reality

There are two broad opposing classes of attitudes to reality (realist vs idealist, material vs mental) with corresponding attitudes to knowledge (objective vs subjective, scientific vs romantic). I argue that these attitudes can be compatible, and that quantum theory requires us to adopt both of them.

Dual Nature of Acid-Fastness **

Acid-fastness is usually defined by the Ziehl-Neelsen technique: staining in carbol-fuchsin, differentiation in HCl-alcohol, and counterstaining in methylene blue.8 As a result, acid-fast substances are red, non-acid-fast materials, blue. Some authors have felt that this property of differential staining resided in one specific type of compound, the mycolic acid type of long-chain fatty acid fo...

The dual nature of epiphysial cartilage.

functions. Such a concept of a single tissue with a double purpose arises naturally from the fact that light microscopy of an epiphysis fails to demonstrate any morphological feature by which the future articular cartilage may be distinguished from that which is destined ultimately to be converted into bone. The epiphysis develops from a uniform mass of hyaline cartilage in the centre of which ...

The Dual Nature of Respiratory Jaw Reflex.

Mathur and Chowdhuri (195'2) described a reflex mechanism, consisting of an increase in respiration rate on opening the mouth, operative in dogs only when their body temperature is raised. This was then confirmed by Kumar (1953) who stated that in majority of the dogs this mechanism starts operating between 40 41°C body temperature, and then quickly disappears beyond 42°C. Kumar and Sinha (1961...
